As described on the previous page, we have Cyanogenmod CM11 running on an LG L7 II.

Here are some useful hints and tricks for the CM11 installation:

Terminal:

Ctrl-C on the terminal emulator is Vol- & C

Tab on the terminal emulator is Vol+ & T

Task-Manager:

since cm does not feature a graphical task manager, how do we monitor the cpu usage?

open the terminal

start “htop”

Useful Terminal Commands:

su

become super user

pm list packages

lists all installed android app packages

ps -c

show running processes with memory usage and cpu load

ps -c | grep app

print cpu load of a particular app (.e.g. com.android.shell)

logcat -s app

show log messages of a particular app (needs to be run with su)

SD-Card:

fix android permissions for the external sd-card

fixes camera to be able to write to the sd-card

steps:

open the terminal and become root: su

cd /system/etc/permissions

copy the file platform.xml to your sd-card

cp platform.xml /storage/external_SD/

now edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.

add an additional group definition for this permission: <group gid=âmedia_rwâ />

and put the modified file back to /system/etc/permissions/

we can’t do this when android is running - SELinux will prevent any modification of /system even with root priviledges

instead we boot into recovery and use the TWRP file manager to copy the file

Shutdown

Vol+ Home Pwr

Mount system

File manager

navigate to modified platform.xml and select it

navigate to /system/etc/permissions and copy it

now we can open the camera preferences and select sd-card as image location

as a nice side effect the restrictions of KitKat on the sd-card are gone: any app is able to write to the sd-card, if it has the WRITE_EXTERNAL_STORAGE permission.

Useful Apps:

There are a couple of useful apps that are not included in the base CM11 installation. Those can be installed either via the Google Play Store or downloaded as apk package from www.apkmirror.com. Here is my favorite selection:
